Kung fu isn’t very good for fighting but you have to look at the history of China and the Boxer Rebellion in particular to understand why. In short, to prevent it from being used in an uprising ever again, the government quite literally took the martial out of the art of Kung Fu which is why wushu is an official sport and kung fu is not.

That said, sanshou, wing chun and jeet kune do have preserved some of the great martial fighting aspects of kung fu. I would’ve agreed that Capoiera is useless until I saw it used in MMA on YouTube. Again, like judo itself, any art can be used martially if adapted properly.

In regards to the intertwined history of judo and jiu jitsu, Dan and David Camarillo are two excellent jiu-jitsu and judo fighters who also pay great respect to the heritage of both arts.
